Useful tutorials for the cloudflare subdomain config. Most first time using the cloudflare have trouble getting the right configuration. This will help you for the settings.
To use cloudflare on a subdomain, a Cname record needs to be setup for the subdomain for cloudflare to work correctly. To do this, you can create a subdomain (lets call it example.headstartcms.net).
You can then login to cpanel and select “advanced DNS editor”. You can then change the record for example from an A record to a Cname record and change the Ip to headstartcms.net.
You can then go into your cloudflare section and enable cloudflare for this subdoman.
